docs: def _find_games(self, week, year, end_week):
          """
          Retrieve all major games played for a given week.
  
          Builds a URL based on the requested date and downloads the HTML
          contents before parsing any and all games played during that week. Any
          games that are found are added to the boxscores dictionary with
          high-level game information such as the home and away team names and a
          link to the boxscore page.
  
          Parameters
          ----------
          week : int
              The week number to pull games from.
          year : int
              The 4-digit year to pull games from.
          end_week : int (optional)
              Optionally specify an end week to iterate until. All boxscores
              starting from the week specified in the 'week' parameter up to and
              including the boxscores specified in the 'end_week' parameter will
              be pulled. If left empty, or if 'end_week' is prior to 'week', only
              the games from the day specified in the 'date' parameter will be
              saved.
